Title: Application of protective metal coatings on to steel
IPC: B60G17/033
Filed: 1966-05-02
Abstract: A method of applying a protective metal coating (e.g. of Sn Zn, Al, Pb or Cd) on to a steel substrate (e.g. wire or strip) comprises the steps of (1) passing the steel substrate through an aqueous fluoride-containing solution and electrolytically treating the substrate therein so that the surface of the substrate is removed, and (2) passing the steel substrate through a molten bath of the protective metal whereby a protective metal coating is applied on to the newly-formed surface of the substrate.  The aqueous fluoride-containing solution may have a pH not greater than 3.5.  It may comprise KF and HF and may also contain an alkali metal chloride, bromide or iodide (e.g. KI).  The electrolysis may be carried out using D.C., in which case the steel substrate is connected as anode, or using A.C.  The Fig. (not shown) illustrates continuous treatment of steel wire.  Both the aqueous electrolyte and molten metal baths are contained in cavity-walled vessels within which walls heating liquid can be circulated.

Title: Improvements in machines in testing cans for leaks
IPC: G01M3/32
Filed: 1939-07-06
Abstract: 530,926. Testing cans for leaks. BLISS CO., E. W. July 6, 1939, No. 19705. Convention date, July 13, 1938. [Class 106 (ii)] The testing unit includes a sylphon in communication with the can under test to which pressure fluid is admitted, means unconnected to, but movable by the sylphon as the latter expands, which means is held in the position reached by means independent of the sylphon. The units are mounted on a wheel 10 mounted on a shaft 11 one end of which is supported in a bearing 12. Each unit has a packing disc 13 against which a can 14 is held by a clamping head 15 operated in a wellknown manner. An opening 16 in the packing communicates with a T-shaped duct 17 in the wheel. From one end of the duct a tube 18 leads to a duct 19 in a valve-ring 20 rotatably mounted on the shaft in facial engagement with a non-rotatable valve-ring 21 having a duct 22 for connection to a fluid pressure source 23. The opposite end of the duct 17 leads into a sylphon 24 on the top of which bears an armature 25 co-operating with an electro-magnet 26. A light spring 28 acts on the armature. A wire 29 attached to the armature leads to a source of current 29a and a solenoid 29b adapted to operate segregating control means 29c. Each sylphon also has a wire 33 connected to a contact 30 movable over a contact 31 on a disc 32 non-rotatable on shaft 11. This contact is connected by wire 32a to current source 29a. Each electromagnet has leads-not shown-connected to a source of current for energizing and de-energizing the magnets as the various can units pass definite points in their rotation. The valve-ring 21 in closely spaced relation to the duct 22 has a duct 34 and adjustable vent valve 35. In operation cans are fed to the machine and clamped in the conventional manner. As the wheel rotates air under pressure is admitted from pipe 23 through ducts in rings 21, 20 and pipe 18 to the can and sylphon. Movement of ring 20 cuts off air pressure. Immediately after charging the port in ring 20 registers with the port 34 and some of the air is vented through valve 35 to bring about a quicker stabilization of the pressure in the can. After venting, the electromagnet 26 is energized and the armature 25 held. If the can is leaky, the sylphon contracts and breaks the contact between the sylphon and armature which break is detected when the can reaches the station at the discharge point, the means 29a, 29b being set correspondingly. After discharge of cans, the electromagnets are deenergized. In a modification, the duct 17 is connected to two sylphons, one of which has pivoted to it a lever the other end of which contacts with the second sylphon the lever supporting the armature at a point nearer the fulcrum-carrying sylphon. An amplified effect is thus given to sylphon movement. In a further modification, the sylphon moves a rod corresponding to the armature 25 provided with a one-way ball clutch which holds the rod in extended position.

Abstract: 860,450. Selective punching devices. ATVIDABERGS INDUSTRIER A.B. June 9, 1959 [June 17, 1958], No. 19734/59. Class 31 (2). A device for selectively punching holes in a tape 40 comprises a plurality of punches 60 co-operable with pivoted bell-cranks 48, 50 carried by a vertically reciprocating slide 39, the arrangement being such that during upward displacement of the slide, arms 48a, 50a of the bell-cranks engage adjustable stops 29, 30 so that the other arms 48b, 50b of the bell-cranks are moved, against the action of leaf springs 54, 55, into operative positions in which they are selectively retained by the energization of electromagnets 17 to 22, the leaf springs being arranged, during the downward movement of the slide, to return to their inoperative positions all bell-cranks not retained by electromagnets during which downward movement of the slide the operative bell-cranks actuate the corresponding punches 60 to punch the tape 40. The punches are supported by spring wires 64 carried by a fixed bridge 31, Fig. 2. The slide 39 is reciprocated by means of cranks 34 mounted on the main shaft 7. At least the arms 48b, 50b of the bell-cranks are of magnetic material. To enable the tape to be fed through analysing means, an actuating member 46 fixed on the slide co-operates with a punch 59 to punch a hole in the tape in each punching cycle. The energization of the electromagnets is synchronized with the motion of the slide by means of a pointer fixed on the main shaft and consisting at least partially of magnetic material, the pointer being adapted to move through an air gap in a magnetic circuit to control the current supply to the electromagnets.

Title: Improvements in cooking, heating or like apparatus for treating tins of food or other articles
IPC: A23L3/04
Filed: 1931-07-10
Abstract: 379,460. Preserving food &c. GAL. VIN, H. D., Cornercroft, Hampton Grove, Ewell, Surrey. July 10, 1931, Nos. 19828 and 20627. [Class 49.] In cooking, heating &c. apparatus for treating tins k of food or other articles comprising a tank a to which the articles k are fed, preferably one at a time, and through which they are passed in a predetermined path for a given time, the articles k are fed to one or other of a series of conveyers h carried by a rotary drum member e, the articles being moved intermittently along the conveyer h while the conveyer is at the same time rotated about the axis c of the drum. Each conveyer h is formed of L-shaped links h<3>, each having a finger adapted to support a can k, and is carried by sprockets h<1>, h<2>. The cans are retained in position on the conveyer by guides f, g, l. Each conveyer is kept from rotating, while it is being carried around the tank a, by a shelf o, Figs. 3 and 4, on which one of the horizontal link fingers rest, whilst a ramp p is engaged by one of the link fingers which is angularly disposed. At the position at which each conveyer is charged through a feed port m with an untreated can, whilst a treated can is discharged through an outlet port n, intermittent movement of the conveyer though one pitch distance is obtained by providing a break in the shelf o and on the ramp p. The finger which is to take the fresh can engages inclined portions o<1>, o<2> on the shelf o which impart the intermittent movement to the conveyer. A member r on the conveyer frame pushes the fresh can along until it is picked up by the finger. When working with steam under pressure, the outlet port n has a compartment s which is flooded with water which is then brought to the same pressure as the tank a and a slide n<1> is opened to allow the tin to fall into the water and be cooled, prior to discharge, by opening a slide n<2>. To facilitate charging the tins pass to the feed port m through a compartment which is first exhausted by a fan m<5> ; a tin is next allowed to fall in by opening and closing a slide m<1>, charging the compartment with steam at the same pressure as in the tank, opening a slide m<2> and finally pushing the tin on to the conveyer h by a rod m<3>. To prevent damage by the tins the slides n<1>, m<1>, m<2> have trip rods m<4>.
